Tb all whom it ma concer o:

Be it known t at we, JOHN J. Dossnn'r and Ema G. SMITH, citizens of the United States, and residents of Syracuse, in the county of Ononda a and State .of New York, have-invente a certain new and useful Lamp-Shade Holder, of which the following is a specification.

This invention has for its object the proing elements are in effective position. Fig.

2 is a vertical sectional view of the lamp shade holder. Fig. 3 is an inverted plan view partly in section. Fig. 4 is a frag mentary sectional view, illustrating the position of the parts when the clamping elements are released. Fig. 5 is a detail view' of a clamping element.

This lamp shade holder comprises, generally, a .body, clamping elements carried by the body in position to engage the lamp shade, an operating element encircling the ,body, and power-transmitting means betweenthe operating element and the clamping .elements.

1 is theJbody which is here shown as tubular to receive an incandescent electric lamp socket, and as provided with an annular flange 2 at its lower end.

3 are the clamping elements carried by the flange 2 and arranged in a circular series concentric with the axis of the body 1, each element 3 being in this form of my invention shown as angular and fulcrumed at itsangle as at 4 in order to have a pivotal or rocking movement. The portions of each clamping element 3 on opposite sides of its angle extend above and below the flange 2 and the portion below the flange is arranged to move radially during the rocking movement of the element and is formed with means as a head 5 for entering the roove usually provided at the upper ends 0 lamp shades or globes.

1, and movable lengthwise thereo As here shown the flange 2 is provided with peripheral notches 6,,and theclampin elements 3 are set into said notches, an each element is provided with notches 7 at its an lo, the notches 7 opening through the side e ges of the clam ing elements in position to receive the pro ect1ons 8 between the .notches 6 of the flange 2.

9 is the operating element, and -10 the powertransmitting member connecting the operating element and the clamping elements 3. The power-transmitting member is here shown as a sleeve encirclin the body E and connected thereto by a pin 11 extending into a lengtlnvise slot 12 in the bod 1, this in and slot preventing turning o the mom or 10. Said member is provided with. an inclined conical flange 13 at its lower end which extends under the upper or tail portions 14 of the clam ing elements 3.

The operating e ement 9 encircles the member 10 and body 1 and is connected to the nwmher 10 by screw' threads. The member 9 bells or flares at its lower end and skirts the flange 2 and the clamping elemunts ii. and bears at its inner face against the edges of the projections 8, thus holding the elements 3 from displacement. The inner face of the bell orskirt of the element 5 bears on the edges of the projections 8 and hence the element 9 is held from axial movement downwardly. The element 9 is held from movement axially in the opposite direction by detachable means on the upper end of the body.

15 is a ring associated with'the body 1 and engaging the upper end of the operatlm element 9 to hold said element 9 from en wise movement upwardly. The rin 15 is keyed to the body 1 in order t be helll from turning movement by a pin 16 projecting from the body into a slot 17 in said ring 15.

19 is a cap threading on the 11 )per end of the body 1 against the ring 15, t 1e cap having a neck 20 for the entrance of the'wires to be connected to the lamp socket, the neck being externally threaded for connection with the chandelier or other support or wire conduit.

In operation, upon the turning of the operating element 9 to move the ower-transmitting member 10 downwau ly into the position shown in Fig. 4:, the clam )ing elements 3 will be released so that the shade elements to operate the same, and an operating element encircling the body and being connected to the power transi'nitting means toaetuate said means, substantially as and for the purpose described.
